The average so far has been $1300 ($24B/18M). No doubt those costs are coming down, but it's because the ONTs are getting cheaper and they're using existing coax.
But those saving disappear when you are starting to deploy into rural areas and you have to string or bury hundreds or thousands of fiber-feet between every home unlike typical tract neighborhoods of MDUs.
BTW I am agreeing with ya here. Costs are coming down , cornings flexible fiber and the newer tools are reducing costs at staggering rates. -- "It's always funny until someone gets hurt......and then it's absolutely friggin' hysterical!"
